SASH-FASTENER.

Specification forming part of Letters Patent No. 49., 159, dated August1, 1865.

To all whom it 'may concern:

Be it known that I, A. H. ROWE, ot' Hartford, in the county oi' Hartfordand State oi' Connecticut, have invented a new and ImprovedSash-Fastener; and I do hereby declareV that the following is afull,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying dra-wings, forming part ot' this specilication, in Which-Figure l represents an inside view of my invention. Fig.2 is averticalcentral section of the same. Fig. 3 is a plan or face view ofthe same.

Similar letters of reference indicate like parts.

This invention consists in a revolving slotted cam arranged in acircular case, in combination with a radially-sliding spring-bolt, in

such a manner that when the device is applied to a sash by turning thecam in one direction the spring-bolt is drawn in and the sashunfastened, allowing it to move up or down. and by releasing the canithe bolt is allowed to drop into suitable sockets made in the side ofthe window-frame at suitable intervals, and in this position it islocked by the cam, and the possibility of a spontaneous unfasteningofthe sash is avoided.

A represents a circular case, made of metal or other suitable material,and provided with a suitable ange, a, and holes b, so that it can bereadily secured to the jamb ot'a sash, as shown in Fig. 3 of thedrawings.

Through the case A, in a diametrical direction, passes the bolt B, beingguided at both ends by holes in the sides ot' the case, and in thecenter by the screw b', which passes through a slot, c, in the body ot'the bolt, as `clearly shown in Fig. l of the drawings. A spiral spring,d, Wound round the shank ot' the bolt has a tendency'to force the sameout in the direction of the arrow marked near it in Fig. l.

In order to force the holt back a revolving cam, G, is applied, asshown. This carn turns on thc central screw, b', and it is provided witha slot, e, which catches over a pin, f, projecting from the headof thebolt, as shown in Fig. 2. The cam is operated by a handle, h, whichprpjects through a segmental slot, g, in the case, and which is securedin an arm, t', ex-

tendingfrom the cam C. Said cam is so shaped that when the bolt isallowed to follow the action of the spring d it is `lockedby said cambearing against the pin f, and by these means the bolt is prevented fromreceding spontaneously. By turning the handle h in the slot g the camacts on the pin f, so thatthebolt is forced back against the action ofthe spring d.

When the case A is secu`red to asash, `asshown in Fig. 3 of thedrawings, and the bolt drops into holes in the side strip of the frame,the sash is locked, and the bolt cannot recede and unf asten the sashuntil the camG is turned. By taking hold of the handle l1l and turningit` in the direction of the arrow` marked near it in Fig. 3 the bolt iswithdrawn, and at the same time by pressing against the handlethe sashcan be .raised to any desired position. On releasing the handle the boltis forced out by the action of the spring, and when itcomes opposite asocket in the strip itdrops in and relocks the sash.

This sash-fastening is intended particularly A. H. ROWE.
